An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-20112 in the wild and no public exploit code.\n\nAffected product: Cisco IOS XE Software. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-20112/ (Markdown: https://insights.sbomify.com/CVE-2026-20112/index.md)","id":"CVE-2026-20112","markdown":"https://insights.sbomify.com/CVE-2026-20112/index.md","name":"CVE-2026-20112","record":{"aliases":["GHSA-mwjg-c924-h42v"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco IOS XE","requires_auth":"high_privilege","summary":"Authenticated attackers can inject malicious scripts into the Cisco IOS XE web interface, enabling arbitrary code execution or data theft.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A vulnerability in the web-based Cisco IOx application hosting environment management interface of Cisco IOS XE Software could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device.\r\n\r This vulnerability is due to insufficient validation of user-supplied input.
